If you had got your Scanjet G4050 unit without any ProLiant ML370R05 driver CD or the latter is lost, you may choose to follow the links below. Without a special Scanjet G4050 driver to your unit, you won’t be able to use all its HP functionality. The basic ProLiant ML370R05 driver from Windows is only able to support the minimum FaxFinder FF120 set thereof. You are really in need of a fully-featured authentic ProLiant ML370R05 driver.
For Scanjet G4050 download, please just follow the Optiplex GX270 link.
